Important: The bonded spacer plate gasket assembly is not re-useable and should be replaced any time it is removed from the transmission.
- Inspect the control valve body spacer plate and gasket assembly (396) for the following root cause:
• | Damaged gasket sealing surfaces |
• | Plugged or damaged screen/seal assemblies (382) |
- Inspect each ball check valve seat (one at a time) on the spacer plate (370) for excessive peening.
• | Place a ball check valve (372) on each seat |
• | Use a flashlight to look for visible light between the ball check valve and the seat. |
- Install 4 ball check valves (372) into the case cover (400), in the positions shown. Use
J 36850
or equivalent in order to hold the ball check valves in the case cover (400).
- Install the 2 larger ball check valves (373) and the 4 smaller ball check valves (372) into the control
valve body (300). Use
J 36850
or equivalent in order to retain the ball check valves in the control valve body (300).
- Install the screen/seal assemblies (382) into the spacer plate and gasket assembly (396).
Important: The bonded spacer plate gasket assembly is not re-useable and should be replaced any time it is removed from the transmission.
- Install the NEW spacer plate and gasket assembly (396) onto the control valve body (300).
- Install the bolts (368) to hold the spacer plate and gaskets onto the control valve body (300).
- Install the control valve body alignment sleeve (410) into the case cover (400).
Important:
• | Use the control valve body alignment sleeve (410) and turbine shaft sleeve in the case cover (400) as guides. |
• | Be sure that the ball check valves do not drop out of the control valve body (300) during assembly. |
- Install the control valve body (300) onto the case cover (400).
- Install the transmission fluid pressure (TFP) manual valve position switch
assembly (395) onto the control valve body (300).
Important: Finger start the bolts to prevent cross-threading.
- Install the control valve body bolts (374-381, 384) as indicated.
Important:
• | Tighten the bolts in a spiral pattern starting with the bolts at the center of the control valve body. |
• | If the bolts are tightened at random, valve bores may become distorted and inhibit proper valve operation. |
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Tighten the control valve body bolts (374-381, 384).
